What do L and R stand for in a car?

The L and R buttons on a car are the left and right rearview mirror adjustment buttons. L corresponds to the left rearview mirror, and R corresponds to the right rearview mirror. The adjustment methods and functions of the rearview mirrors are as follows: Adjusting the left rearview mirror For the up and down position, place the distant horizon in the center, and for the left and right position, adjust it so that the car body occupies 1/4 of the mirror's area. Key points for adjusting the left rearview mirror: Place the horizon at the midline of the rearview mirror, then adjust the edge of the car body to occupy 1/4 of the mirror's image. Adjusting the right rearview mirror Since the driver's seat is on the left, the driver's grasp of the situation on the right side of the car is not as easy. Additionally, due to the need for roadside parking, the right rearview mirror should have a larger ground area when adjusting the up and down position, occupying about 2/3 of the mirror's area. As for the left and right position, adjust it so that the car body occupies 1/4 of the mirror's area. Key points for adjusting the right rearview mirror: Place the horizon at the 2/3 position of the rearview mirror, then adjust the edge of the car body to occupy 1/4 of the mirror's image. The rearview mirror is a tool for the driver to directly obtain external information about the rear, side, and lower parts of the car while sitting in the driver's seat. Its function is to facilitate the driver's operation, prevent traffic safety accidents, and ensure personal safety. All countries require that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.
I just got my driver's license and was a bit intimidated by the letters on the car. The most common ones near the steering wheel are L and R, which stand for left turn signal and right turn signal. For example, L is the left turn signal—you flick it when turning left to alert cars behind you to avoid a collision. R is the right turn signal, used when turning right or changing lanes. The operation is simple, but don’t underestimate it. The first time I drove, I forgot to signal and almost got into an accident, which scared me half to death. Now, I’ve made it a habit to signal before every turn—developing good habits is key. By the way, some cars have other functions, like the L and R buttons on the rearview mirror adjustment, which adjust the left and right sides for a clearer view. New drivers should practice these basic operations more—safety first, don’t be as flustered as I was at the beginning. Remember, lights are the car’s language—don’t stay silent, okay?
Having driven for over 20 years, I'm very familiar with car details. L and R basically mean left and right, most commonly seen on turn signals. The control stalk on the left side of the steering wheel: push L down for left turn signal, R down for right turn signal. After activation, it automatically turns off, making it both convenient and safe. This feature is especially important during rain or at night - signaling early gives other drivers reaction time to avoid rear-end collisions. Occasionally these letters indicate left/right audio channels in sound systems (like adjusting balance when playing music) or show fault warnings on the dashboard (but don't panic unnecessarily). As a veteran driver, I recommend regularly checking if the lights work to avoid trouble from bulb failures. In short, L and R are fundamental driving language - mastering them makes roads smoother.
As a stay-at-home mom, I often drive my kids to and from school, so the L and R on the car are very familiar to me—they stand for the left turn signal and the right turn signal. The operation is simple: the L button activates the left turn signal, and the R button activates the right turn signal, alerting other vehicles to your intended direction. This design is very thoughtful. For example, when making a right turn at the school gate, I use the R signal to ensure my child's safety when getting out of the car. I also use the L and R buttons on the rearview mirror to adjust the view and prevent blind spots. Ignoring these details can lead to dangerous situations. A friend of mine once rear-ended another car because she forgot to use the turn signal—a lesson learned the hard way. Paying attention to these small details ensures safe travels for the whole family.
